What it's built forOpen these in the simulator →

This telescope was built to capture, not to squint.

Point it, tap a target, and it stacks a live image on your phone — color and faint detail no eyepiece will show you. The trade is simple: the experience lives on a screen, not at an eyepiece.

The view people remember

Andromeda, wider than the Moon.

A vast soft oval with a blazing core — two and a half million light-years of galaxy, spilling well past the field of view under a genuinely dark sky.

01What it's good at

What it's best at — and the trade-offs.

114 mm of aperture at f/4 gathers enough light for detailed processed deep-sky views.
Best at
✓114 mm of aperture at f/4 gathers enough light for detailed processed deep-sky views.
✓Unistellar's enhanced-vision processing pulls color and structure out of light-polluted skies.
✓Fully automated pointing and tracking make it effortless to run and to share.
✓The app supports citizen-science campaigns like occultations and comet monitoring.
Trade-offs
!There is no true optical eyepiece; you view on a device.
!It is a deep-sky instrument, so planets remain small and low in detail.
!The experience is tied to Unistellar's app and ecosystem.
!The price is high relative to cheaper smart scopes with comparable basics.
02In plain English

What These Numbers Mean

114mm · f/4 · 450mm FL · Integrated Alt-Az GoTo
Aperture
114 mm
Four and a half inches is large for a smart telescope, where 50 to 85 mm is more typical. That light grasp is what lets it build a recognisable image of a faint galaxy in a few minutes of live stacking rather than an hour.
Focal length
450 mm
Short focal length paired with a fairly large aperture gives a wide field and a bright image. Nebulae, clusters and larger galaxies frame naturally; small planetary nebulae and the planets are not this system's strength.
Focal ratio
f/4
Fast, which is what makes live stacking practical: each short frame carries enough signal that the image visibly improves every few seconds while you watch.
Optical design
Sealed smart reflector
A mirror system with a camera in place of an eyepiece and no optical viewing at all. The whole experience happens on a phone or tablet, and several people can watch the same live view at once.
Weight
9.2 kg complete
About 20 lb including the integrated mount and tripod. It is portable in the sense that it fits a backpack, but it is substantially heavier than the small smart telescopes it competes with.
Mount
Integrated alt-azimuth GoTo
The mount aligns itself by plate-solving the real sky, then finds and tracks any target you select, with no setup routine to learn. Alt-azimuth tracking means it stacks many short exposures rather than taking long ones.

Editor’s Take

The eQuinox 2 is a "smart telescope," which works nothing like a traditional one: no eyepiece, just a small scope pointed at a camera you run from your phone. It finds and tracks its own targets and stacks short exposures live, so a faint grey smudge builds into a bright, colourful galaxy on screen in a minute or two, a technique called electronically-assisted astronomy (EAA) that cuts through city light far better than an eyepiece can. You give up the through-the-glass view and any optical upgrades, but nothing is easier or more shareable.

Premium step-up

Unistellar eVscope 2

Adds the Nikon-codeveloped OLED electronic eyepiece for through-the-eyepiece viewing, the eQuinox 2 is app-only.

Budget pick

ZWO Seestar S50

A much cheaper entry into smart imaging if the eQuinox is a stretch, with a smaller 50 mm aperture.

As a sealed, app-driven convenience scope it stays useful for travel and quick city sessions, but committed observers usually add a larger smart scope or an open imaging system within a year or two rather than relying on it alone.
